Financial services firm USAA — one of the San Antonio’s largest employers — has jettisoned 300 more jobs, a belt-tightening move that comes two weeks after it posted its first annual loss since 1923, the Express-News reports. Company officials told the daily that the firings were spread across most of its offices and business lines. The enterprise still has 37,000 workers, roughly half of them in the Alamo City, where it’s headquartered.
